The cable is not in focus in the CCD images, but the focus is known from the work on the lam,ps on the mast. Since the cable is linear a somewhat different ‘halo signal’ would be seen. On windy nights the cable oscillates so it may be hard to get enough images where the cable is at rest wrt the source that illuminates it – the Moon.

We have tried that with the lamps on the navigation tower — but the results are not unambiguous. We were thinking of using the mountain as a knife edge to test this as we got splendid data a few nights back of the moon rising from behind the mountain edge. More to follow!
